To all whom it may concern: I

Be it known that I, JOSEPH E. Lemma, a citizen of the United States,residing in Man- Chester, in the county of Hillsboro and State of NewHampshire, have invented a new and useful Improvement in Bobbins forCotton- 'this general character being illustrated in Letters Patent of-the United States o.

788,806, granted May 2, 1905.

In the Letters Patent referred to, the

sleeve or tube (termed'a cone in said Let-,

ters Patent) is connected with the s )indle by means of cars orprojections which extend from the inner end of the sleeve intolongitudinal slots in the spindle, said ears bending substantially fromtheir extreme rear endsthe ends which join the tube-diagonally or atobtuse angles into the slots. It has been found in practice that 'intubes or sleeves, whether conical or with parallel sides, provided withears of this shape, the thread is frequently pinched against or underthe inner end or edgeof the tube and is thus broken. M invention has forits principal object to o viate this difficulty by preventing the threadat or about the time when the sleeveis being released by the unwindingof the thread from coming in contact with the said end or edge of thesleeve, the thread being prevented or guarded from or against suchcontact by the shape of the ears or projections themselves. As theimproved ears send oil the thread from the adjacent end or edge of thetube, pinching and consequent breaking of the thread is prevented.

' The nature of the invention isyfully doscribed below, and illustratedin the accoinf panying drawings, in. which- Figure 1 is a view of asindle with my im proved sleeve in'position t iereon, the thread eingnearly unwound'from the bobbin, and that which is left on the spindlebein guarded or fended oil fromcontact witht 0 tube by the ears orprojections which extend into the slots in the spindle. Fig. 2 is alongitu- Specification of Letters Patent. Application filed March9.1907. Serial-No. 361.4%.

I dinal section of a portion of the spindle with the ears in the sameposition as in Fig. 1. Fig. 3 is a view in pcrspectiveof the sleeveremoved.

Similar letters of reference indicate corresponding parts.

a re resents the spindle, and b the head thereo said spindle beingprovided with the opposite longitudinal slots 0. On the portion 6! ofthe spindle between the slots and the head is a loose tube or sleeve e,referably of substantially even diameter throughout its len th, the rearouter end oi-the sleeve bein orrned up into an annularfiange f, may beengaged by any, suitable mechanism which is exposed to the direct blowsof the feeler. The inner end of the tube e is provided with two cars orprojections, which are opposite each other and extend into the slots 0.Each of these ears is integral with thesleeve, and consists of the broadportion 9, which is in a, strai ht line with the portion of the side ofthe tube from whioh'it extends and the portion h which bends inward atsubstantially right angles with the portion 9 into the slot 0. Theortion h is comparatively narrow and the e ges of the portion 9 broadenregularly, as shown from the portion 71. to the body of the tube.

- In practicalo oration, when the thread is nearly unwoun and the sleeveis loosened in its position, said sleeve is checked in its a proachtoward the thread by the ears, and tl ie thread comes in contact onlwith the portions h of said ears, being he (1 oil from the adjacent edgeor end of the sleeve by the ong enoughto prevent any possibility'of thethread bein reached and inched by thesleeve and t us broken, T e widthof the portion 9 is' suflicient 'to insure stren th to preventsaidportion from bending, an as the portion 9 is bent inward at rightangles there is no danger of the thread riding up onto said portion.
